Abstract: Foam thermoplastic injection molding apparatus and method produces structurally superior foam injection molded products. The process includes plasticating solid polymer to a polymer melt; accumulating the melt in an accumulator having a telescoping inlet, which allows the first melt which enters to be the first to leave the accumulator; combining a preselected amount of melt with a preselected amount of gas in bubble form to form homogenized polymer foam; shearing the homogenized polymer foam to reduce the size of gas bubbles; and injecting the polymer foam through a special gate assembly into a mold. The gate assembly has a removable nose which remains with the mold, allowing the foam to expand within the mold but not allowing the foam to escape the mold. The process and apparatus allow low molded-in stress products to be produced, and can process recyclable thermoplastics, either single materials or mixtures. Thus, no segregation of materials is required.

The inlet channel comprises a first and a second segment, which first segment is of a configuration tapering from the inlet opening (26) towards the mould compartments, and which second segment has dimensions so as to to no substantial extent hinder liquid or water from flowing through the second segment. At the transition between the first and the second segment of the inlet channel, a constriction is defined, serving the purpose of generating a venturi effect for generating a relative pressure drop within the constriction for closing the inlet channel at the constriction as liquid or water is flowing from the second segment of the inlet channel through the constriction towards the first segment. <IMAGE>   <IMAGE>
